<p>A moveable toy consisting of a base and a motorized vehicle. The base includes a track having a central groove ending in openings at either end. The track includes verticle teeth on the exterior thereof which cooperate with a drive gear held in the vehicle to drive the vehicle along the track. Rotors having notches on the top surface are rotatably held for movement in one direction in the openings at each end of the central groove in the track. Once the motor of the vehicle is actuated, the vehicle travels along the track. The travel of the vehicle is guided by a blade cooperating with the groove, and a guide held in a slot. When the vehicle arrives at either end of the track, the blade leaves the groove and is captured between the notches on the rotor. The drive gear continues to operate, and since the rotor cannot rotate in the direction of movement of the drive gear because of cooperating stop means in the base and a supporting foot, the vehicle rotates the base by the teeth formed around the end of the track. The base rests on a surface, and the weight of the vehicle at the end of the track presses the end down, and cams or lifts up the opposite end of the base. The base may then more easily rotate around the stationary foot, approximately 180.degree. to allow the vehicle to continue back into the groove toward the other end of the track and for further movement of the toy in the same direction.</p> |
